When Jon is chasing the blue van, the same light blue Ford station wagon is run off the road twice by the van.
The two cars that crash immediately after the van crashed in the road construction zone (one of which crashed into the van) came from a section of road that was closed and under construction.
When Jon and Grossman first attend to the gentleman with a flat tire, in the background there is a green car that drives past. A few minutes later, the same car drives past the scene but in the opposite direction. Considering this is a freeway, the driver would not have been able to drive by the scene twice in opposite directions in a short place of time.
Following the RV accident involving Muriel and Frank, CHP are seen directing traffic past the accident scene. Among them are two cars which drive past, a white jaguar and another green car. The same cars were also seen earlier when Jon and Grossman attend to the man on the freeway with a flat tire.
Once again, the same red Chevrolet Caprice Estate station wagon appears several times. Examples are when the old couple stops along the road, then a moment later after the crash.
When Jon and Barry attend to the RV on fire, Barry spots a person inside. Jon is seen breaking the front window to allow Barry to climb through to rescue the watchman. It seems a lot of effect to do this as Jon is seen breaking into the RV via the main door. He breaks the smaller window, puts his hand through and manages to unlock and open the door. The two could have easily done this in the first place and been inside the RV a lot quicker.
The security guard that was about to take a nap in Andy's motor home would have suffered heat stroke as it was not powered up to run any air conditioning.
One of the CHP officers Ponch recruited for the team had a full beard, which was prohibited by CHP regulations.
